Application filed March 7,

This invention relates to brick or stone:

I masonry tools particularly to a combination tool for working recessedmortar joints to' produce the very decorativevetle'ct commonly known asraked courses. An'object of the invention is to provide a simplecombination tool which may bemanipu'lated to perform substantially allthe necessary operations in producin the raked course effect inanyor allpartsbif the wall. I I Further objects and features of theinvention willbecome apparent from the follow ng description relating to a theaccompanying. drawing wherein I have shown my preferred form.

Usually separatetools are used for removing the surplus mortar frombetweenadjacent bricks or blocks to the required depth and for afterwardpacking and smoothing the mortar. This is because the scraping, asmatter of fact, calls for more than a simple tool inorder to make speedin operating on the joints in the more open parts of the wall and inorder 'to reach the mortar in recessed corners and the lil fQI examplewhere two wall faces join at aright angle, the smooth-. ing or finishingoperation also calls for more than a. simple tool because the cornerrecesses and the .cross? that is the vertical joints, calls for adilierent sortof tool shape than may he usedto advantage on therelativelyflong line joints, that is'to say the horizontally extendingjoints. Consequently as far as I knowtherehas not been developed asatisfactory'tool for performing all the necessary operations inproducing the raked course ef'tectprevious to myinvention.

In its preferred form my invention is embodied inatriangularly shapedtool, one slde member-of the triangle being formed curved at both endslike alhockey skate runner, thls' being the smoothing tool. Another sideor leg of the triangle is recessed to bold. are movable'andlongitudinally ustable scraping tool. The third side or-leg bracestheother two and functions as a gauge to dete mine the depth or thescrapingtool; Inci dentally, thistriangle shape, while not entirely essential,is especially convenient becauseof clearance in using the tool in abruptcorners as when two wall faces join at right angles. The side firstmentioned, namely the smoothing tool portion, serves as a handle whilescraping, and the recessed side serves as a handle while smoothing,these sides be. ing preferably substantially the same size in 1927..seriaino. 173,274..

order that the workman is not inconvenienced by changing from one sizeof the handle toanother.

In the drawing Fig.1 is a perspc'otive'view of the complete tool; Fig. 2is a side elevation thereof; Figs. 3' and 4C are diagrammatic viewsshowing the use of the tool in the of different character and location.1

Referring in detail t'o the drawing, 1 is the smoothing portion ofthetool; 2 is the re joints cessed handle member containing the adjustlegandthe baseand its smoothing surface 1 is substantially planular for aconvenient distance and the ends curve inwardly as at 1 and 1?. I isless abruptly curved than the end 1 and is narrower from about the point1- to the very end. This narrow portion begins before i the curve inorder that the whole curved end may be usedv fo-rfsmoothing between the,nar'

It will be noted that the end 1 row joints as "where the bricksareplaced closer together than the standard mortar joint-i 1 The portion1? is sharpened at its end as atil 'to serve as a scraper, referencebeing had to Fig. 3 wherein this narrow'p'ointed end is shown asgouging. out excess motar in a recessed corner of the'wall, a portion ofthe horizontal mortar bed being indicated at'M and'the bricks'in thecourse below this mortar bed. at B. The desirability ofthe three sidedtool becomes apparent in this figure as it will be seen thatconsiderable rotatingmovement' may be given the tool while in thisgouging out position, in order'to quickly remove the necessary amount ofmortar.

I The opposite end of the member 1 is also sharpened as at l, to serveas ascraper if desired. However, this sharpened end 1 will bevery'little used because when digging the mortar out of corners itis-much easier to use the narrower end of the tool.

The leg 2 maybe secured in any'convenient manner to the leg 1 as ascrew, and similar fastening means mav be provided between the side 3and leg 1 as at 3, the side 3 curving outof the leg at 3, the portion 3beingwidenedas shown at Fig. 1' to serve as gauge, the gauge being wideenough to span two adjacent bricks on each side of themor tar joint. Theside 3 may be secured in any convenient manner to the leg 2 as bywelding.

As shown in Fig. 9., the leg 2 is hollow for a considerable Xtent toreceive doub'leended scraper 5 which is longitudinally ad ustable handlewhile-scraping, the other of saidpor; trons serving as the handle wh lesmoothing, V and means on one of said portions pro ecting :later'allyfrom the tool to serve as a depth prising two mutually rigid divergingmem- -i and preferably made of tool steel or the like I .for hardnessand to allow slight flexibility.

,The preferredform of scraper is a flat piece of metal bent up at itsendsas'at 5.

Suitably secured in a boss 2 is a 'set screw 6 shown enlarged at its endand knurled.

The inner end of the screw bears againstan intermediate portion of thescraping tool and slightly bends it in suchmannerthat the tool is bourneagainst the bottom of the recess in the leg 2 at two points, oneateachside of the screw. 'lhis arrangement insures hold ing of thescraper rigidly in place.

It. will be seen that the scraper may projected as "far beyond the gaugeportion 3 as it is desired to scrape back the mortar. In

other words, the scraper may be adjusted for any depth of joint recess.and this depth will be maintained. by reasono'l the gauge portion 3*bearing againsttlie bricks on either side of the joint, and preventingthe tool from gouging any deeper.

In usingthe tool, all the line courses may be efiectively scraped out bylong strokes of the scraper tool 5, as well as the vertical'or crossjoints. The joints at corners and recesses maybe scraped out by thepointed end 1? as previously mentioned and shown, inFig.

termediate. portion of the leg 2, sm oothing 8, and during this scrapingthe operator holds the tool. by grasping ,thel ntermed atc portions ofthe leg 1. For smoothing the opera tor simply reverses the'tool,grasping the inout the'line joints by the member 1, the cross jointseither by the portion. n01; 1, pref- 0It1bly'I",$.S illiisti'atedinFig.4. v

, WhileIhave described the tool as comrisin f three, eneral parts forminthe leps I h \J O ofatrianglc, it'is tojbeiunderstood thatthissubstantially straight but rounded at one end to serve as a mortarsmoothing tool, and an other portion being formed to receive and supporta longitudinally adjustable scraping tool, thefirstmentioned portionserving as the gauge forthe tool.

2. A tool of the character described combers, one member having aplanular mortar smoothing surface and having one end curving inwardlyfrom said surface toward the tool, said other member being recessed ametal tool, adapted for scraping mortarand qad ustably seated in saidrecess, and'means carried by said other member for clamping the tool inadjusted position.
